To all whom it may concern:

Be it known that I. Eon Ann E. Broneno son, a citizen of the United States, and a resident of Toledo, county of Lucas. and State of Ohio, have invented a certain new and useful Improvement in Radiator Shutters; and I do hereby declare the foliowing to he a full, clear, and exact description of the invention, such as will enable others skiiieri in the art to which it appertains to maize and use the some.

This invention relates to air-controliing arrangements for radiators on automobiles and similar apparatus. Shutter arrangements have previously been used on euijo' mobile radiators for controiling ihe fiovr of air through the radiator, whereby "the desired temperature of the cooling fluid may be controlled, but, a far as I am aware, the shutter arrangement for controlling the air has been of such construction that it is hard to operate. and therefore, thermostatic control of the shutters has been more or less unsatisfactory.

One object of my invention. is, therefore, to provide a shutter arrangement that wiii hove minimum friction of movement, so that it can beoperated by the usual thermostat devices on the market.

Another object is to provide both autorustic and manual control.

A,furi-her object is to connectindicator devices to the shutter arrangement, so that the driver will at all times know What the position of the shutters is by glancing at a suitable place onthe dash or instrument board.

Further objects will be found in the appended description, reference being had to the drawings, in which:

Fig. 1 is an elevation of a radiator and other parts ofan automobile with my radiator shutter attached.

Fig. 2 is a front view of the radiator with attached shutters.

F ig. 3 is a section taken on the line A-A of Fig. 2.

Fig. 4 is a sectional plan taken on the line BB of Fig. 5.

Fig. 5 is a sectional elevation taken on the line CC of Fig. 4. v I

Fig. 6 is an elevation'of the indicator.

Referring to the drawings, my improvementconsists, broadly speaking, in having .13 and on the end sheiis 5 end 6 at each Sid@-0f the rediaior 'Z. The journals or shafts e of the shutters are secured to pinion members 9, which mesh with a rack member 10 sliding ehrough openings in the projections 3 and The rack member 14) has e. central slot end adjacent sides of this are provided with gear teeth 11, 12, which mesh with alternate pinion members, as will be evident from an inspection of Fig. 3.

At the top of rack member 10 is attaehed a iever 13 "which may be pivoted st 14% at.

the reer part of the shell 5, or at an other suitehle place. The end 15 of this ever is attached to the movable member 16, attached at its other end to any suitable thermostat 17! The particular thermostat used is no part; of my invention, and e detailed description of it is unnecessary, inasmuch as thermostatic consrols are old and Well known in the art.

The rack member 10 may be connected for manual control in various ways. but I have provided a series of gear teeth 20 at one side, which mesh with a pinion 21. This pinion is secured to a shait 22, which extends to the dash or instrument board 23, and is provided With an, indicator 24. Instead of manipulating the pinion 21 by means of the indicator, I prefer to utilize another member, such as tube 25. for the manuel control. This tube or pipe is adapted to clutch and unclutcli with the pinion 21, so that the manual control may be thrown out of engagement when the automatic or thermostatic control is in working condition. Various positive clutches may be used, but I prefer to form cavities in the pinion, which are adapted to mesh with projections 26 on the end of the tube 25.

The tube 25 passes through a bearing member 27 secured to the radiator shell 5, and the other end passes to the indicator device on the dash or instrument rd. This luster consists of s, bushing 01" foiri 'ulo 25% passing through tho mshrumoni, hoard, 1th a fiungsmsinbcr 29 V attached to the hoard. Tho bushing 28 is preferably wronged with s dismetov soficiently lsrge to permit the uss of a spring; 30 therein, one endof Whic may bear against it collar 33'. sscui sd to tho tube 25, and the other end against the menu h s? 2 In this Way the spring "csnds to maintain the clutch in operative position.

To the end oi the tube attached a collar 32, to whicl'i is attached a. handle 33 having a lug 34: adspied *to seat in a depression. 85 in the cloi'atod portion 36 of the flange or plate 529 when in :2 cortain position; and in a series ofdoprsssionsfi'? Wlisn in othsr positions. v

The opsrstion of the improvement as described is as follows: When the ongrine of th automobile is cold, the thsz'most is 1'? will maintain the ssriss of shutters 1 in closed position, or substantially so, as shown in 3, As thoooling watcrheatsup,d11s to tho'yunning of the engine, the thermostat- Wiligrsduslly move the rock 10 upward in Fig. 3, and this will mono the-first shutter 1' in a clockwise; direction, the next lower shutter in. a countsr-clockwiss direction, and. so on. More and more air will he ermitted to pass between. the shutters so through the radiator 'Z in this way as the engine heats up. The cooling Water will, therefore, be maintained at the desired temperature by the thermostatic control of the radiator shutters. I I

As the rack member 10 moves upward. the pinion :21 and shaft 22 are i'otatsd counter-clockwise and the indicator '2 moves to the loft inFig. S to give a visible indication of the position of the shutters, When tho indicator hand is in the extreme, right hand position, as in Fig. 6, the shutters are closed and when it is over to the extreme position at the left, the shutters are fully opened. The iudicatonhand will take a position somewlioi'g between these extreme positions as the slmttcl s are moved by the thermostat device. When the thermostat do vice is controllingthe radiatorshutters, the handle 33 of the manual dcvico will he moved so that the in? 34; rests in dprossion 35, and. since this is higher than tho lowor portion of the. plate 29, the tube 25 will he maintained in an outward position, where the lugs 26 of the positive. clutch will ho free oi the pinion. The manual control will, therefore, not hamper the automatic control, When, however, the automatic con- Lrol gets out or order, the operator can rotats handle around onto the lower portion of plate 29, where in some position the lugs 25 will pick up the pinion by clutching ini/o the depressions thoyoin. Movo fluent of the handle 33 then will either open oi oioss she shutters by rotating tho pinion 21-, and the shutters will be maintziine'd in position. Also, the spring will maintain the 1 lever in the other position by yieldingly holding it in deprossion 35. I

my improvement the indicator 24 gives the position of the radiator shutters, regardless of Whether the manual or the automatic control is in operative position.

l have described one particular embodiment of my improvement, but it will he apparent that various modifications may be made without departing the invention. I
